ASTEC SUN AA23650 RS5 400W Power Supply – Overview

The ASTEC SUN AA23650 RS5 is a 400 W AC server power supply unit designed primarily for Sun Microsystems / Oracle server systems like Sun Fire V240, Netra 240, and other models. 02 or “Sun 300-1846” in server parts catalogs. 
It may be a hot-swap type PSU, suitable for redundant server power configurations.

This unit offers a stable and reliable 400W output for mission-critical server environments.


Key Features & Benefits

  • Power Output: 400 W — sufficient to support multiple server components and peripherals.

  • Worldwide Input: Supports 100–240 V AC input (50–60 Hz), making it usable in global power environments.

  • Server Compatibility: Commonly used in Sun Fire V240, Netra 240, and similar Sun / Oracle server models.

  • Hot-Swap Capable: Can be used in servers that support redundant power supplies; ensures minimal downtime when one PSU fails.

  • Compact & Efficient Design: Optimized for server racks to reduce wasted space and improve cooling efficiency.

  • Safety Protections: Built-in overcurrent, overvoltage, and short-circuit protection to safeguard both PSU and connected hardware.


Compatibility

This PSU is suited for server systems originally using the ASTEC / Sun 300-1846 AC module. Compatible systems include:

  • Sun Fire V240

  • Netra 240

  • Some configurations of Netra 440

  • Other Sun / Oracle server models using 300-1846 or ASTEC AA23650 modules

If your server uses part numbers such as 300-1846-01, 300-1674, or 300-1846-02, this is likely a compatible replacement.


Buying Guide & Tips

  • Check Original Part Numbers: Always match the server’s original PSU part number (e.g. 300-1846-01) to confirm compatibility.

  • Verify Connectors: Ensure that the power supply’s connectors (both AC input and server interface) match your server’s socket.

  • Redundancy Support: If your server supports redundant PSUs, purchase two units to operate in failover mode.

  • Cooling and Airflow: Maintain proper airflow in the server chassis—this PSU is designed for rack environments with good ventilation.

  • Warranty & Condition: Ask for warranty (refurbished vs new) and health test results, especially for used or pulled units.

  • Buy from Reputable Suppliers: Always source from trustworthy server parts providers to avoid counterfeit or damaged units.
